Tried out the new Blade Tail equipment (Roundhouse Whip Straight)

Just like the name, it's a bladed tail. Its movement feels like swinging a short whip left and right to hit the enemy. Looking at its performance, I thought there might be better equipment for this slot, and since it's a double attack, short for a whip, and has a weapon-specific cooldown, it seemed unusable... It's mediocre as a melee weapon, but after the double attack, if the enemy isn't downed, there's a roughly 1/3 to 1/2 chance it will automatically follow up with an extra attack, allowing you to take them down quickly. I wonder if the AI judges: 'Enemy is staggered at close range → then land a high-power follow-up attack.'? It depends on how much it's grown, but it sometimes pulls off surprisingly skillful plays, which is interesting.
